Abstract: Multicast and unicast communication among computing devices across different local area networks (LANs) and without static IP addresses is supported by assigning an instant-share (InS) address to an individual computing device. The InS address is recognizable by a dedicated router located in the Internet and enables the dedicated router to communicate with the individual computing device. The individual computing device embeds an InS address of a destination computing device in a data message to form an extended data message, and sends the extended data message to the dedicated router. The dedicated router then forwards the extended data message to the destination computing device. A group member contact synchronization among different computing devices in a group without Internet connectivity is also supported. Local lists of group members from different computing devices are collected. The most-recent one is used to update the local list of group members of a computing device.

Abstract: Systems and methods are described for communications between computing devices via a stateless high-volume network address translation (“NAT”) service. The stateless high-volume NAT service manages high volumes of connections between networks by encoding at least part of the information needed to manage a connection in an encoded IPv6 address, which is then used by a NAT device or application as its sending address when relaying data from a source to a destination. The encoded IPv6 address may contain information such as the IPv4 address of the source, the IPv4 address of the destination, the protocol used to communicate, the source and destination ports, and the like. When the destination sends a response to the encoded IPv6 address, the NAT device decodes the IPv6 address to obtain the encoded information, and then uses that information to deliver the response to the source.

Abstract: Forward Error Correction (FEC) techniques that generate independently decodable resource blocks are beneficial for Successive Interference Cancellation (SIC) demodulation. One FEC technique for generating independently decodable resource blocks includes mapping locally decodable FEC codeblocks into unique resource blocks such that substantially all of the bits of the FEC codeblock are carried within a single resource block. The locally decodable FEC codeblocks can be generated from different FEC encoding modules or from a common FEC encoding module. Another technique for generating independently decodable resource blocks includes encoding a stream of information bits into low-density parity-check (LDPC) codeblocks having high ratios of inward peering parity bits. These high ratios of inward peering parity bits allow substantial portions of each LDPC codeblock to be decoded independently from information carried by other LDPC codeblocks.
